So in Egypt, in Aswan down in the south, they regard the sun as being vertical - this is near to the equator - and they worked out how far away from the vertical the sun was if they measured it from the north of Egypt, in Alexandria, which is on the Mediterranean coast.
Jadi di Mesir, di Aswan turun selatan, mereka menganggap matahari sebagai vertikal - ini dekat dengan khatulistiwa - dan mereka bekerja di luar seberapa jauh dari vertikal matahari jika mereka diukur dari bagian utara Mesir, di Alexandria, yang di pantai Mediterania.
